<SquiggleEditor initialSquiggleString="sample(normal(0, 10))" />
## Converting between distribution formats
Recall the [three formats of distributions](https://develop--squiggle-documentation.netlify.app/docs/Discussions/Three-Types-Of-Distributions). We can force any distribution into `SampleSet` format
<SquiggleEditor initialSquiggleString="toSampleSet(normal(5, 10))" />
Or `PointSet` format
<SquiggleEditor initialSquiggleString="toPointSet(normal(5, 10))" />
## Normalization
Some distribution operations (like horizontal shift) return an unnormalized distriibution.
